Diffractive opticalElements

By micro-structuring glass surface, our diffuser tailors laser intensity profiles. While the far-field pattern becomes Gaussian when laser is input on typical diffusive material (e.g. frost glass), our diffuser can shape the laser circle or rectangle and control the intensity profiles (flat-top or 1/cosnθ). Our cut-off profile make little light diffuse outside the projected area, making it high efficiency.

Basically an optic refers to a type of rifle scope or reflex site etc. A good example is a the Zenit-Belomo PSO-1M2-1.

DOE has micro structured surface relief patterns which cause light diffraction. By engineering the diffraction, DOE can split, homogenize, and focus laser beams. A few examples of output beam patterns are illustrated below.

In AGC, we are developing and producing DOE using technologies cultivated though production of optical pickup and optical communication components. Our one-stop engineering service supports our customers from design through large volume mass production using originally developed simulation tools, materials, and rapid cycles of design and process optimization.With accumulated skills and experience through our long-term technology development, our DOE enables low 0th order transmission, wide FOV, and large number dot projection. Using glass, our DOE also has high reliably against thermal, humidity, and laser damage.

In recent years, 3D sensing technologies have been applied in distance measurement face unlock, online payment, security, automotive, LiDAR, etc. Each application requires different metrics, and stereo vision, structured light, and time of flight (TOF) are widely used depending on the applications as summarized in the Table. Structured light technology reconstructs projected patterns created by shadow mask or DOE. TOF technology uses diffuser, and it measures light travelling from a light source, hitting a target, and reflected back to a sensor.In AGC, we are providing various solutions for 3D sensing (e.g. IR transmitting cover glass, glass ceramic packaging substrate(GCHP™), optical filters, and lenses) as well as DOE and diffuser. The figure below shows how our technologies are used in 3D sensing applications.
